PROJECT DESIGN DOCUMENT (PDD) Title of the project activity: Papop Biogas and Renewable Energy Project in Thailand Version number of the PDD: 01 Completion date of the PDD: 29/11/2016 Project participant(s): Papop Renewable Company Limited Swiss Carbon Value Limited Host Party: Thailand Sectoral scope and selected methodology(ies), and where applicable, selected standardized baseline(s): Sectoral scope: 13 ACM0014: Mitigation of greenhouse gas emissions from treatment of industrial wastewater – Version 06 Estimated amount of annual average GHG emission reductions: 113,835 tCO2e/year Version 06.0 Page 1 of 66 CDM-PDD-FORM SECTION A. Description of project activity A.1. Purpose and general description of project activity The proposed Papop Biogas Project (“the proposed project activity”) involves the installation of a new Upflow Anaerobic Sludge Blanket (“UASB”) for wastewater treatment and biogas recovery at the Thai San Miguel Liquor (“TSML”) distillery (“TSML distillery”) located in Amphor Tha Muang, Kanchanaburi Province, Thailand. The proposed project activity is being implemented by the Papop Renewable Company Limited (“Papop”) as a builder, operator, transfer scheme, which will be handed over to TSML after a period of 9 years. The TSML distillery produces alcohol spirits and as a part of the production process generates large amounts of wastewater, which has high organic matter content. Currently, wastewater is treated in an anaerobic lagoon and the anaerobic conditions lead to the production of biogas that is released directly to the atmosphere. The biogas produced contains methane, which when released to the atmosphere is a direct source of greenhouse gas (“GHG”) emissions. The TSML distillery currently operates two fossil fuel boilers for heat production. The combustion of fuel oil results in the production of carbon dioxide, which is also a direct source of GHG emissions. The purpose of the proposed project activity is to use the biogas generated by the UASB for heat generation in the TSML boilers and for electricity generation in a newly installed engine. The electricity generated will be exported to the Thai national electricity grid. The proposed project activity will result in emission reductions from the avoidance of methane emissions from the anaerobic open lagoon, the avoidance of carbon dioxide emissions from the combustion of fuel oil in the TSML boiler and from the displacement of grid sourced electricity which includes fossil fuel based electricity generation. The estimated emission reductions are 113,835 tonnes of CO2e per year. Contribution of the proposed project activity to sustainable development The proposed project activity will deliver sustainable development benefits and has been assessed in line with criteria for CDM projects by the Thai Designated National Authority (DNA)1. 1. National Resources and Environmental Dimension The project activity reduces GHG emissions through the avoidance of methane emissions from the existing open lagoon; The project activity reduces GHG emissions through the avoidance of carbon dioxide emission from the combustion of fuel oil in the TSML boiler The project activity reduces air pollutant emissions such as oxides of nitrogen, oxides of sulphur, carbon monoxide and particulates, through the reduction in the combustion of fossil fuels. The project activity reduces the carbon intensity of the Thai national grid by reducing the emission of GHGs on a per MWh basis across the entire system; The project activity reduces the consumption of non-renewable natural resources (through replacing fossil fuel sourced grid electricity). 2. Social Dimension During construction, the proposed project activity is expected to employ around 120 temporary workers. The proposed project activity is expected to employ at least 9 people for operating the biogas plant. The workforce will be trained to operate the UASB plant, resulting in an improvement in the skills and technical knowledge of plant operators. 1 http://www.tgo.or.th/english/index.php?option=com_content&view=article&id=24:sustainable-development-criteria&catid=27:approval- process&Itemid=45 Version 06.0 Page 2 of 66 CDM-PDD-FORM 3. Development/Transfer of Technology The proposed project activity requires the use of both imported and Thai technology, which provides an opportunity to promote and disseminate the successful application and integration of technologies for replication across Thailand. 4. Economic Dimension The project activity leads to the utilization of renewable energy and contributes thereby to energy security and savings in expenditure on imported fuel. The project activity increases the employment opportunities for the local people by setting up an industrial unit in the area. This will directly promote other income generation sources like local suppliers, manufacturers, small shop owners etc. The project activity contributed to the employment of local people both in the skilled and semi-skilled category during the construction phase. In light of the information above, the project activity strongly contributes to sustainable development. The proposed project activity is implemented purely on a voluntary basis. There is no regulation that requires implementing such a project. A.2. Location of project activity A.2.1. Host Party Thailand A.2.2. Region/State/Province etc. Kanchanaburi Province A.2.3.

Technologies and/or measures The technologies and measures to be employed and/or implemented by the project activity: The project activity is implemented closed to the TSML factory in order to treat the wastewater generated by the distillery production process. The distillery factory has an installed capacity of about 75,000 Liter of liquor per day. The proposed project activity involves the installation of a UASB digester in between the exiting sump pit and anaerobic lagoons. The exact location is provided in section A.2.4. Anaerobic treatment system The UASB consists of concrete reinforced lagoons, which are covered with a biogas storage dome made from PVC sheeting. The UASB is a methanogenic digester, which uses an anaerobic process whilst forming a blanket of granular sludge, which is suspended in the tank. The wastewater will be entered to the UASB digester at the base of the system and will flow upwards through the blanket where it is degraded by anaerobic microorganisms contained in the sludge. With an average inlet COD of 179,9372 mg/l and a COD removal efficiency of around 95%3, the production of biogas is expected at 49,277 m3 per day (with the methane percentage being around 55%). The treated wastewater leaves the UASB digester at the top of the lagoon, and will flow into the exiting anaerobic lagoon (storage Pond 9), before being discharged to the existing evaporation ponds. The biogas is produced as a by-product of the wastewater treatment in the UASB digester and captured in the biogas storage dome. The project activity utilizes the biogas for thermal and power 2 One-year historical data of TSML distillery factory 3 Technology provider Version 06.0 Page 4 of 66 CDM-PDD-FORM generation purposes. The biogas will be passed through a biogas dryer before being combusted for thermal generation in the existing TSML distillery boilers. The thermal oil boiler is designed with a capacity of 16 TPH. The remaining biogas will be used for electricity generation in two gas engines. The capacity of each engine is 952kWe. The biogas will be first treated to reduce the sulphur content by the H2S cleaning system (Bio-Scrubber) with biogas capacity of 23,000m3/day. In the case of emergencies or surplus, biogas will be flared by enclosed flaring system having a capacity of 1,000 Nm3/hour at 30 mBar. The electricity generated by gas engines will be exported to Thai national grid under the Very Small Power Producer (VSPP) Scheme. Figure 4 illustrates the proposed project activity of wastewater treatment and biogas utilization process. The project activity is expected to have a lifetime of 15 years, which is confirmed by the technology supplier. Technology, measure and know-how transfer The UASB system is supplied by Papop Co,Ltd., a local technology provider. The gas engine is manufactured by a Spanish manufacturer (Guascor). The bio-scrubber and the enclosed flare are manufactured by Thai companies. The bio-Scrubber is developed by Papop Renewable Company Limited. The enclosed flare is manufactured by BKE Combustion Control Limited. It presents that the project activity is leading to a significant transfer of technology from developed countries to Thailand. Furthermore, all the suppliers will provide necessary training for the operation and maintenance of the equipment in the project activity, which will further enhance the skill set of the local employees. The technology existing prior to the implementation of the project activity: The scenario existing prior to the project activity is identified as the baseline scenario later in section B.4 of the PDD. In the absence of project activity, the wastewater generated by the distillery process have been treated in the anaerobic open lagoon (pond no.1 and 2). The figure 3 shows the diagram of baseline boundary. The wastewater has a high organic loading with COD of 175,794 mg/l that is based on one-year historical data.
